There are some things here that bothered me so much I made an edit:
Whats with all the perspective flips?
The shadow UNDER the window, the door, the huge horizontal gap in the tiles.
It messes with your eyes.
Anyway I circled what I changed.
In short - tile lines too thick horizontally, door glass too tall and funny things going on with perspective, window too tall and shadows where you shouldn't see them, chair legs too thin ( compared with other chairs ), cylinder cuboard doors, and whats with the fridge handles?
The tiger is a nice touch but needs some work on the face.
